RESILIEN T WHEEL.

Applicatun led March .This invention relates to spring tires, and more particularly to tires .adapted for use in connection with automobile wheels, and one ot'my objects is to produce a sprlng or resilient tire core which may be used with the common and ordinary type of pneumatic casing. r

Another'object is to produce a non-puncturable tire which is of strong, durable, efiicient and inexpensive construction.

A further object is to providey means for assisting certain springs forming a part of the invention, to cushion the shock or jars transmitted by the irregularities of the roadway.

lVith the objects named in View, the invention consists in certain new and useful improvements as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawing, in which Figure 1 is a side View of a casing equipped with a. resilient core embodying the invention, the casing and core being broken away to more clearly disclose certain features of construction.

Figure 2 is an edge view of the same With the casing broken away to disclose the meeting ends of the outer member of the core.

Figure 3 is an enlarged section on the line III-III of Figure 1.

Figure 4. is a view similar to Figure 3, but taken at right angles thereto on the line IVIV thereof.

Figure 5 is a fragmental perspective View of a portion vof a part of the core member.

Figure 6 is a perspective view of a foot piece or base member forming a part of the core construction.

ln the said drawing, where like reference characters identity corresponding parts in all ot the figures, l represents an internally channelled split ring of'semi-circular form in cross section, and made of steel or the like.` At one of its ends the ring is formed with a flange 2 for interlocking engagement with the other end, as shown in Figure 1, and said ring is provided with a pair of openings 3 on opposite sides of the joint for the insertion of suitable prys or levers for convenience in compressing the ring when it is desired to place it Within an automobile casing 4, as will hereinafter appear. The inner face of the ring is formed integrally with a plurality of spaced inwardly pro- 16, 1925. serial Naf-15,879.

jecting pairs of ears 5, to Whichthe outer ends of tubes or cylinders 6 are hinged by means of pins 7,. it being noted that the tubes are slightly longer than the cross-sec-A tional inte'rnal radius of the casing andare provided with closures 8 adjacent the hinge pins.f. *f

A continuous inner ring or lcore member 9 of externally channelled form and semicircular in cross section, is adapted to be fitted Within the tire casing and to press againstthe side walls andl beadsthereot as indicated in Figurey 3; and fitted between said rings or core members 1 and 9, are a series V`of coiledy expansion springs 10, held in position by frictional engagement withA the ears 5. of the outer ring or lcore member 1. The central portion of the member 9 is formed with a plurality of spaced rectangular openings 11, through which are projected the ear 14 carrying the stemsvor plungers 12 which are snugly received within the tubes 6, and equipped at their outer ends with washers 12a or the like, for entrapping and compressing air in the tubes 6 to form air cushions and rebound checks. The plungers are hinged on pins 13 at their' inner ends between pairs of ears 14 carried by short arcuate plates 15 adapted to press against the rim 16 of the Wheel to provide a long bearing to cooperate with the nonrotatable fit of the ears 14 in said openings 11.

In assembling the device, the outer member 1 is first sprung inwardly to overlap its f split ends and decrease its diameter in a manner similar to the manipulation of the ordinary rim when placing same in a casing, and is then inserted into the casing and its free edges are caused to engage or interlock, it being understood that the member will be of proper size for the particular casing and will snugly fit against the tread and side walls thereof. The springs 10 are now inserted and engaged with the ears 5 of the member 1, through the open side of the casing, and then the inner member 9 is disposed Withinthe casing and outer member, effecting the compression of the springs 10, care being take-n to properly locate the member 9 so that each spring shall be alined with one of the square openings 11 of the member.

The plungers 12 are now inserted into the tubes 6 through the openings 11, said openlll ings being of rectangular shape to snugly receive lthe earslll ito hold 4the device lagainst accidental rotation. The engagement of the ears 14 with the ring openings 11 also main-V tains the parts of the device Vin their proper respective positionsby guarding against invidual creepage. l y

The transversely split rim I6 of the wheel is now positioned within the tire in the com= mon and ordinary manner7 the iat foot or base portion 1-6 fof the plungers pressing anjainst'saidrim and guarding against the accidental tilting of the parts when subjected to the jars and vibrations of actual service. In the use of the device, it will be noted that each plunger` l2 traps air within its respective tube 6 and that the compressi-on of iair between the ends or closures 8 of said tubes and the plungers will form an `effectual air lcushion for retarding the relative movement of the springs7 thus providing a shocl; absorber and rebound check.

From the above description, it will be apparent that I have produced a device possessing the features of Vadvantage -set forth as desirable, and while I have described and claimed the preferred embodiment of the same, it is to be understood that I reserve the right to make all changes properly falling within the spirit 'and scope of the appended claims.

I claim:

ll. The combination of a wheel r-im and tire casing thereon, spaced inner and outer ring members fitting in the casing one within the other7 the outer member being transversely bowed 'outwardly and the inner member transversely bowed inwardly, plates fitting flatly against the peripheral surface of the rim and provided with lugs projecting outwardly through the inner ring member, and telescopically related tubes and plungers pivote'd at their o'uter ends to the outer member and at their inner ends to 'said lugs.

2. The combination of a'- wheel rim and tire casingthereon, spaced inner and outer ring members 'fitting in the casing'one within the other, the outer member being transversely bowed outwardly and the inner member transversely bowed inwardly, plates fitting flatly against the peripheral surface of the rim and provided with lugs projecting outwardly through the inner .ring member, telescopically related tubes and plungers pivoted at their outer ends to the outer member `and at their inner ends to said lugs; and springs between and 'exerting lforce outwardly an'd inwardly on the outer and inner inembers respectively.

In witness whereof I hereunto aflix my signature. y
